SPECIFICATION forming part of Letters Patent No. 657,355, dated September 4, 1900. Application filed September 30, 1899. Serial No. 732,152. (No model.) l

To LZ1 whom/ zit may concern:

Beit known'that I, JOSEPH NAGLER, a subject ofthe Emperor of Germany, residing at Toronto, in the county of York and Province of Ontario,Canada,have invented certain new and useful Improvements in Tide-Motors, of which the following is a specification.

My invention relates to improvements in tidem0tors; and the object of my invention is to provide a motor that will be operated by the ebb and flow of the tide and by means of this motor to pump air or water to any suitable reservoir; and it consists, essentially, of a suitably situated and constructed cistern or well which contains a suitably held and constructed float and an air-pump operated by said ioat for the purpose of pumping air to any suitable reservoir, as hereinafter more particularly explained.

Figure l is a general perspective view of my I preferably constructed of masonry and is built with a solid foundation near the seashore where the ebb and flow of the tide takes place.

A is a metal sheetingwhich preferably` lines the major portion of the tower A.

B is a partition dividing the tower A into a well or cistern C and the air-compressing well or cistern C and is connected by the piston-rod C2, having bearing in the partition B, to the piston-head D.

E is the top of the air-compressing chamber D. Y

e is a packing between the sheeting A', the

partition B, piston-head D', and top E of the air-compressing chamber. This packing e makes the air-compressing chamber D perfectly air-tight, and also makes the pistonhead D air-tight. The float C is preferably made hollow and air-tight, as shown. The said ioat is made somewhat smaller than the well or cistern C and is guided in its upward and downward movements by the guide-casters c, secured to or forming part thereof, as shown. As will be seen from the drawings, the tower Ais hollow for a short distance below the Water-chutes F, which, it will be u nderstood, introduce the water into the well or cistern C beneath the iioat C. 1

G represents iron gratings secured over the intake-openings of the water-chutes F to prevent any foreign matter from getting into the well.

2 is a cock for the purpose of permitting the ingress and egress of air as required of the air-compressing chamber D.

3 is a cock for the purpose of drawing o water from the air-compressing chamber D should any at any time get therein.

4 is a cock for permitting the ingress and egress of air of the lower portion of the aircompressing chamber D, which is below the piston-head-D, when the said piston-head is in its lowest position, as 4 shown in Fig. 2. This cock also enableswater to be drawn from the lower portion of said chamber D should any get therein.-

When my `tide-motor is used for the purpose of pumping water, as shown in Figs. l and 2, into the reservoir 5, a suitable pumping apparatus is used in connection therewith.

Having described the principal parts in volved in my invention, I shall now describe its operation. We will suppose that the tide is owing. Consequently the iioat C in the lower portion of the cistern or well C as the 4quantity of Water Within said well increases is gradually forced upwardly. This forces the air from the chamber D through the pipe J into the pumping apparatus, from which the. water is forced to a suit-able reservoir. It will of course be understood that the iioat C', which I propose making of metal, will be heavy enough to pull downwardly the pistonhead D' during the ebb of the tide.

As shown in the drawings, the'bottom of the well C is closed. This prevents the rush of water through the intake-pipes/F from undermining the foundation of the .tower A when my tide-motor is constructed in the manner shown.

IOO

The improved tide-motor which I. haveeinvented contemplates theemgployment: off a Vertically-elongatedA hollow tower, which' is perfectly constructed of masonry and has its foundation embedded in the earth firmly.

The interior of this hollow tower is equipped ,A

' with a cylindrical iln-perforate lining', the

upstroke ofv said piston-head,

lower end of which is closed, and this lining is divided by a transverse division-plate., soyI as to produce an upper compression-chamber i apparatus illustrated in the present drawings :is not claimed herein, but is covered by the claims of a companion application iledconf currently herewith.

and a lower power chamber or well. The surgesof the waves are freetoenter thepower chamber or wellof the tower through the in.- clined inlet-ducts, which open throughl the outside of the tower substantially at the lowthe towel-'at ilood or ebb tide.

is connected operatively to the piston-head through the medium of a rod which plays slidfably iu an opening'of thedivision-plateand j this piston-head has its peri-meter packed. so

as to have tight engagement with that part of u the cylindrical lining of the tower which constitutes the compression-chamber. For the pro pei-in gress of air tothe compression-chamber above the piston-head l provide the valveinlet 2, the valve of which is arranged, to open automatically on the downstroke of the piston-head and to close in likemanner'on the I employ a similar air-inlet 4 on a plane below the limit of movement of the piston-head' in a downward direction, which air-inlet is in commu.- nication with the compression-chamber and islikewise equipped withl the valvethat opens automatically on theupward movementv of the piston-head andr closes in like manner on the downward movementof the piston-head. The described arrangement ofthe valved airinlets makes the compressionchamber and the piston-head constitute a double-acting air-forcing mechanism in that thepiston-head compresses'air on the up and down strokes thereof. The eduction-pipes IJ are in comi munication with the com pression-chamber 'substantially on the plane of the valved= airipletS 4. 2, .respectivelybsaid eduction-pipes having suitable check-valves, asl `heretofore described." `A valved drain 3 is in communication with the compression-chamber at a point between the valved air-inlets 2 4, preferably at a point above the limit o`f the down- -iward movement of the` piston-head, so as to What I do claim as my invention, and de- A sire to secure by LettersPaten't, is

A tide-meter comprising a vertically-elon gated hollow .tower provided with a continuouscylindrieal lining, closed at itslower end, and wi-ththe inclined water-inlet: ducts which open through the .outside of the tower substantiall-yf 0n the plane of the low-water line, a division-plate fixed within said cylindrical lin-ing and dividing the latter into a lower power-chamber* and an upper compressionchamber, a buoyant' float in said lower powerchamber, a. packed piston-head fitted tightly in the upper compression-chamber, a pistonrodsl-idably Iitted in the division-plate and connectedtothe floagtandl to: the piston-head,

la valved air-inlet 25 opening into the compression-chamber above the upper limit of the travel'of the piston-head, another valved inlet 4 opening into the compression-chamber `at a: peintA below the lower limit of travel of said piston-head, a drain-cock 3 between the air-inlets, and eductionpipes leading from the compression-chamber on the planes of theinlets 2, 4, respectively, substantially asdesc-ribed.

In Wit-ness whereof Ihave hereunto setmy hand inl the'presence of two witnesses.
